Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
A study (DuPont Safety, Health & Environmental Excellence Center ) was performed on a marine species: Acute toxicity to daphnids (marine water) : EC50-(96h) = 0.47 mg/L (nominal concentration)
A study (Hüls AG.) was performed on a freshwater daphnids: Acute toxicity to daphnids (freshwater) : EC50-(24h) = 2.9 mg/L (nominal concentration)
So, 1,5,9-cyclododecatriene can be considered as very toxic to daphnids.
Key value for chemical safety assessment
Additional information
3 experimental results were available in order to assess the toxicity of 1,5,9-cyclododecatriene to daphnids. However, 1 study could be considered as unreliable due to the insufficient documentation.
One study (DuPont Safety,) was performed on a marine species: Acute toxicity to daphnids (marine water): EC50-(96h) = 0.47 mg/L (nominal concentration)
The last study (Hüls AG.) was performed on a freshwater daphnids:Acute toxicity to daphnids (freshwater): EC50-(24h) = 2.9 mg/L (nominal concentration)
So, 1,5,9-cyclododecatriene can be considered as very toxic to daphnids.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
